To all whom it may concern:

Be it known that T, Eruns'r Onrrrunnn, of the city of Calgary, in theProvince of Alberta, Dominion of Canada, have invented certain new anduseful Improvements i... Tire Sealing Compositions, of which thefollowing is the specification.

This invention relates to an improved composition of matter for sealingpneumatic res or like containers, and the objects of the invention areto provide an inexpensive composition which will occupy small bulk,which when mixed with water will form an effective tire fillingcomposition adapted to quickly seal any puncture in a pneumatic tire andprevent the escape of air therefrom.

The principal ingredients of the composition of matter are an adhesive,such as gum arabic, a relatively heavy filling material such as Whitelead and talc, and a relativel light filling material such as powderedan granulated cork. The ingredients'prior to use are mixed with water insuitable proportions.

The preferred proportion and iedients are as follows:

Water 2 quarts. Granulated cork 4L. oz. Powdered cork 2 oz. Talc ll lb.White 1ead 8 oz. Gum arabic 2 oz.

These ingredients are to be thoroughlytion will at once tlow thro 1 thepuned v npecincatiou of Letters Patent. Application filed February 3,1917. rial llo. ltddlt.
